Can we make the actual test function __init as well? I don't think it
should be _necessary_ for this to work, but I'd like us to have the
option of entire tests being marked __init, and so discarded after
boot.
This seems to work here if the test is marked __init, and the
example_init_test_cases and example_init_test_suite are marked
__initdata.
But, as mentioned in the previous patch, that might not work if we
need to ensure example_init_test_suite and other metadata still
exists. So maybe we can document that here?
Otherwise, looks good.
